Versuchsvorschrift
Following the procedures of Examples 241 and 287, 3-(5-bromo-6-fluoropyridin-2-yl)-5-(pyridin-3-yl)-1-((2-(trimethylsilyl)ethoxy)methyl)-1H-pyrazolo[3,4-c]pyridine and (R)-benzyl azepan-4-ylcarbamate hydrochloride were reacted to give (R)-benzyl 1-(3-bromo-6-(5-(pyridin-3-yl)-1-((2-(trimethylsilyl)ethoxy)methyl)-1H-pyrazolo[3,4-c]pyridin-3-yl)pyridin-2-yl)azepan-4-ylcarbamate, which was dissolved in Trifluoroacetic Acid (5 mL) and Methylene chloride (5 mL), and treated with Trifluoromethanesulfonic acid (5 eq.) and Triethylsilane (5 eq.). The resulting mixture was stirred at room temperature for 2 days. The mixture was then concentrated, and the residue was purified by reverse phase HPLC to afford 313 as an off-white solid (14.2 mg, 25.5%) over two steps. 1H NMR (400 MHz, DMSO) δ 9.24 (s, 2H), 8.91 (s, 1H), 8.61 (d, J=3.6 Hz, 1H), 8.42 (d, J=8.0 Hz, 1H), 8.35 (s, 1H), 8.03 (d, J=8.0 Hz, 1H), 7.62-7.51 (m, 2H), 4.00 (d, J=14.6 Hz, 2H), 3.90-3.81 (m, 2H), 3.77 (dd, J=11.4, 6.7 Hz, 2H), 3.67-3.59 (m, 3H), 2.18 (s, 1H), 1.98 (dd, J=31.3, 18.3 Hz, 4H), 1.75-1.59 (m, 1H); ESI MS m/z=464.01 (M+1)
